'10 ALL 'HOM l'l MAY CONCERN:

Be it known that I, E. I t. GARDINIER, of Brooklyn, in the county of Kings, and State of New York, have invented a certain new and useful Improvement on Machines for Sizing and Felting Hats, of which the follow ing is a full, clear, and exact description, reference being had to the accompanying drawing, forming part et' this specification, and in which- Figure 1 represents a top view or plan of a machine eonstruetcd according to my improvement; and

Figure 2, a longitudinal vertical section of the same.

Like letters indicate corresponding parts,

My invention relates to apparatus for sizing and felting hats or other work, in which the hat-bodies or rolls into which they are formed are sized or felted by passing them between nn adjustable bed and endless belt or apron, operating in connection with a. suitable hot-water bath or battery; and the nature 0l: myinvention consists in e. novel combination of inclined endless belt and inclined adjustable bod, of vat-form, that, in connection with the belt, is made not only to present the necessary sizing surface, but also et its lower or feedend to form, by means of an outer ense or box, a bath, for a portion of its length, to the hat-bodies or rolls during'the early portieri of their travel through the machine, und a dry or drying tra'vel for the remainder, and whereby a separate bath or battery may be dispensed with.

Referring to the accompanying drawing, A is an outer box or vessel, the sides of which, or posts connected.

therewith, serre to support the end drums B that carry the endless belt or apron C, set in motion, say, by a pulley, D, on the shaft of one of the drains. The belt or apron C is inclined by Aa, suitable disposition ofits drums. E E :tre rollers arranged in close contiguity to euch other between the end drums, and running across the box or vessel for the belt, on its interior face, in its lower run or travel, to bear against, so as to secure a. comparatively straight and suiiieiently rigid sizing surface to the exterior' of the belt in its lower run. F is the bed also set inclined for operation in connection with the endless belt or apron C, in the manner hereinbefore referred to. This bed F is turned up at its ends to form feed and delivery inclines, and serving, in conjunction with the box, bath, or vessel A, asa. vat or bath for the lower half, or thereabouts, of its inclined lengt-h, through which the habbodies or rolls are passed, boing entered at or over the lower end of the bed F, and worked between the endless belt or apron and bed, along the upper uninirnersed halt' or portion of the space contained between the bed and aprox., and over the top or higher end of the bed. The hed F may rest, at its opposite ends, on springs I), to gire an elastic pressure or hearing on the hat-bodies or rolls passing between it and the apron, and said bed may be adjusted by screws to regulate the pressure of the springs; it being necessary, on first pnssing through the hat-bodies or rolls, when the feit is tender, to subject them to a light pressure, and as they become harder to gradually increase the pressure in repassing them, or to regulate the pressure according to the description of goods heilig worked. The Iluid or water contained in the box A and lower inclined half or portion of the bed F may be heated by steam-pipes arranged in tbe box A below the bed, or by any other suitable means.

From this description it will be seen that the hat-bodies or rolls, in their early or iirst half or portion of travel through the machine, pasa through a bath forming part of the sizing apparatus, and subsequently through a. dry, or drying, or unilnmersed portion, whereby the operation of first softening the bodies and afterwards working them is or may be accomplished without the aid of a separate bath or battery, und labor and time proportionately eeonolnized, while the work is more efl'eetually accomplished, the bodies or rolls leaving the hath in a gradual or easy manner, and the Working of the bodies being better secured by rolling them up an ineiine.

What I claim as my invention, and desire to secure by Letters Patent, is The combination with the inclined endless belt or apron C of the inclined adjustahleior self-adjusting partly sublimi-ged bed F, and box or bath A, substantially as und for the purpose o1' purposes herein set forth.
